Hello, I am new to Matlab and got a question to ask. I have created a .m file which plots a cosine graph. For simplicity, say time=0:T/999:T; x=cos(2*pi*time); plot(time,x); Then this will create a plot with cos(2piT) with domain of 0~T. I will like to export this to other .m file so the file can read this graph and calculate the frequency of graph. But I'm stuck as how I can export this graphical data to other .m file. Because if I just lookup data on x, it will just give out an array of 1000 values and not knowing its domain(time), I can not calculate the frequency. Hope this makes sense. Will appreciate your helps!
